Please elaborate. Haven't heard this before and since I'm considering
one of these units and I have soft water (3-4 dGH, 2-3 dKH) I am really
interested in what/why/how.

As for compressed gas, which I use now, it has drawbacks. My biggest
complain is having to refill the tube since it's very expensive over
here, don't know about the US. You also have to get a magnetic valve
unless you want to add CO2 overnight (expensive in Sweden, maybe not 
where you live).

Lots of fish is also a way of providing more CO2 but then follows 
added cleaning-labor.
